Bianchi had Columbus make them special tubesets, as well as the Celeste sticker to go with the set. The tubing is SP gauge on the down tube and chainstays, I'm not sure about the forks, and SL everywhere else. The idea was to get a bike that is stiff in the bottom bracket, yet comfy and compliant on the bumps. It works. Albert Eisentraut was the first American builder I know of to use this principle extensively, and I've built a few frames that way myself. On a large frame, it makes a stiffer bike than an all SL bike, but rides more comfortably than an all SP bike. Bianchi was also one of the few Italian makers to properly match a different fork rake with each
head angle.
